LUBBICATOR FEED-CONVERTING- Means.

invented certain new and useful Improvements in Lubricator-Feed-Converting Means, of which the following taken in connection with the accompanying drawings, is a specification.

The, invention, relates to lubricator feed converting means for lubricating joints in automobiles and similar mechanism, and the object of the improvement is to provide a simple and eflicient means whichis capable of quick adjustmentinto or out of coincidence so as to change from a plunger type of lubricator such as would be useful foroil and fluid lubricants to a screw type for pressing out heavy greases or other heavy lubricants by means of a screw plunger which is revolubly mounted in the plunger head; and the invention consists in the novel features and combinations hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspec tive view of the lubricator from the plunger end. Fig. 2 is a diametral sectional view of the lubricator showing the preferred construction. Fig. 3 is a plan view of the screw cap for the lubricator barrel showlng the slots in the same for the flat plunger rod and adjusting knob; and Fig. 4c is a plan view of the slotted adjusting plate within said cap and turned by said knob. Fig. 5 is a perspective view of the plunger head showing the preferred arrangement of the same. Fig. 6 is a sectional view of a portion of the barrel with the plunger cap thereon and adjusting plate on the inside of said cap, the slots or notches being turned out of coincidence or at right angles to one another in said cap and adjusting plate to force the turning of the threaded plunger rod.

Like characters of reference refer to corresponding parts in the several. views.

The numeral 10 designates the barrel of the lubricator. The barrel 10.has the plun-,

ger screw cap closure 11 at one end, and the screw cap delivery spout closure 12- at the other end, which screw cap is extended in the tubular spout 13, having the oil tip 14.

The screw cap 11 has the slotted and threaded opening 15 through its center to Specification of LettersjPatent, 'Pa tented J 11119 6 1922 'Application filed October 21, 1920. Serial No. 418,395.

receive therethrough the flat plunger rod lo' which has the thread 17 along each of its opposite edges, and the crosswise handle 18 for turning the same.

The plungerrod 16 is revolubly mounted at its inner end 19 in the sleeve 20 in the plunger head, which plunger head referably has the central portion 22am the cup-shaped covering 21.

An adjusting plate 28 fitting within the cap 11 has the threaded and-slottedopening -29 therethrough tofit upon and recei've'the flat threaded plungerrod 16, a knob 30 b'e- 111g screwed into the plate 28 and slidably workable in the slot 31 in the cap 11, a shoulderbeing provided on the knob 30 to hold the plate 28 firmly in position within the barrel 10 and cap 11.

It is now apparent that the knob 30 and plate 28 can be given a quarter turn in the slot 31, thereby turning said plate 28 into or out of engagement with the threaded edges 17 of the plunger 16 according as it is desired to use the lubricator for oil or grease.

It is obvious also that the cap 12 can be unscrewed from the barrel 10 in order to fill said barrel with oil or grease, and when returned to place, for oil the slots in the cap 11 and plate 28 maybe turned into coincidence so that the plunger will slide freely back and forth through said cap and plate, thereby pressing the oil out of the 13 with its full sized opening, and the knob 3O given a quarter turn, thereby bringing the threaded openings 15 and 29 out of coincidence and at right angles to oneanother as shown in Fig. 6, enforcing the use of the screw plunger in pressing out'the' grease through the tube 18.

I claim as new:

1. A device for'use with grease guns for converting a screw feed to a slide feed in cluding a member having a screw threaded opening and having a slot extendingdiametrically across the opening, a plunger rod having a pair of parallel fiatsides slidable" through the slot and having its remaining sides threaded to engage with the threads of the opening, a rotary member having a corresponding threaded opening and slot the y latter movable into and out of register with the slot of the first member-and a member constituting the sole means for connecting the rotary member to the first named member so as to hold the rotary and first named member against relative lateral movement and formed to allow of turning of the rotary member.

2. A device for use with grease guns for converting a screw feed to a slide feed including a member having a screw threaded opening and having lateral openings extending therefrom, a plunger rod formed to slide through the openings and having threads to engage the threads of the threaded opening, a member having corresponding threaded and lateral openings which latter in one position registerwith the lateral openings of the first member, and combined means c011- stituting the sole; connection between the members to allow of relative turning thereof but to hold said members against relative lateral movement and for providing a finger grip to effect relative turning of the members a 3. A device for use with grease guns for converting a screw feed to a Slide feed including amember having a sorew threaded with the diametrical slot of the first named member, and an operating part carried by the rotary member and extending through the curved slot of the first member and arranged to abut the end walls of theourved slot to cause the diametrical slots of the members to be brought into and out of register. t i

In testimony whereof I have afiixed my slgnature in the presence of two Witnesses.
